yes, a lot as expected (multiple disks using LVM) so no attempt to |
| 24 |
configure the disks for high performance. The compiles were quite slow, |
| 25 |
but thats fine because I could still use the desktop. The only |
| 26 |
interactive app that didnt work well was the win2k instance running in |
| 27 |
qemu - it did work, though slowly, and when the other jobs were over and |
| 28 |
it could get more cpu time it came back to around normal. qemu is |
| 29 |
somewhat borderline on this machine in any case - been on it for 6-7 |
| 30 |
years though :) |
| 31 |

| 32 |
Some apps that were swapped out had a very short delay while the pages |
| 33 |
were retrieved (mainly noticable on firefox), but the before/after |
| 34 |
impression was the difference between a very short pause and what used |
| 35 |
to happen - time to take the hand off the mouse and lean back in the |
| 36 |
chair and wait for FF to catch up. |
| 37 |
|
| 38 |
Keep in mind this is a relatively low memory, very old/slow 32 bit |
| 39 |
system I am using. |
| 40 |
|
| 41 |
and after running this for a couple of days, yes, I am still happy with |
| 42 |
it and this gives the old beast a new lease on life :) |
